Save to your folder(s)
I found this excellent tutorial on how to save JPEG images from Flash. You will need the Adobe JPEG Encoder class which can be found here: http://code.google.com/p/as3corelib/. You will also need some server-side action which in this case was done in PHP

Copy this code and paste it in your HTML 
  1. import com.adobe.images.JPGEncoder;
  2.  
  3. function createJPG(mc:MovieClip, n:Number, fileName:String) {
  4.  
  5. 	var jpgSource:BitmapData = new BitmapData (mc.width, mc.height);
  6. 		jpgSource.draw(mc);
  7. 	var jpgEncoder:JPGEncoder = new JPGEncoder(n);
  8. 	var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);
  9.  
  10. 	var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream");
  11.  
  12. 	//Make sure to use the correct path to jpg_encoder_download.php
  13. 	var jpgURLRequest:URLRequest = new URLRequest ("download.php?name=" + fileName + ".jpg");
  14. 		jpgURLRequest.requestHeaders.push(header);
  15. 		jpgURLRequest.method = URLRequestMethod.POST;
  16. 		jpgURLRequest.data = jpgStream;
  17.  
  18. 	var loader:URLLoader = new URLLoader();
  19. 	navigateToURL(jpgURLRequest, "_blank");
  20. }
  21.  
  22.  
  23. //createJPG(movieClip, quality, fileName);
  24. createJPG(myMovieClip, 90, "myDog");
  25.
